That thermometer will be 25 dollars. 15 dollars! I'm not going to spend 5 dollars!
That's great - any pics of it boiling, or any pics of the digital setup? My guess is that the rubber stopper will allow much more true temp readings....
I decided not to use the digital. I have the termometers on the HLT and MLT, so no boil. I think you're right on the true temp readings :)
